How about the following?
----------------------------------------------------------------
require 'tk'

evloop = Thread.new{Tk.mainloop}
text = TkText.new(Tk.root).pack

i = 0
n = 10000

Tk.root.protocol(:WM_DELETE_WINDOW){
  if Tk.messageBox(:type=>'okcancel', :message=>' Realy? ') == 'ok'
    printf "Bye ...\n"
    exit
  else
    #ignore
  end
}

while (text.exist? rescue false)
  if (i += 1) % n == 0
    text.value = <<EOS
This is GUI #{(i / n)}
Time is #{Time.now.strftime("%Y-%m-%d %I:%M:%S")}
EOS
    printf "This is command line #{i / n}\n"
  end
end
